BACKGROUND OF THE INVENTION

The present invention relates generally to carriers for rollators. More particularly, this invention pertains to foldable vehicle receiver hitch mounted rollator carriers.

Rollators are used by people to enhance mobility. Generally, users of rollators are elderly individuals who are substantially independent and able to safely drive a vehicle. It is difficult for these users to lift their rollator several feet high to place the rollator in the trunk of a car. A user may strap a rollator to a platform or basket style cargo area mounted in a vehicle's receiver hitch, but it is difficult and time consuming to secure the rollator to the cargo area. Withwith separate straps and ropes.

Referring to FIGS. 1-4, a carrier 100 is operable to support and secure a rollator 102 for transportation. The carrier 100 includes a first tube section 104, a second tube section 106, a first cradle 108, a second cradle 110, a third tube section 112, a fourth tube section 114, and a clamp 116. The first tube section 104 has a first end 120 and a second end 122 opposite the first end 120. The second end 122 of the first tube section 104 is operable to engage a mount 130. In one embodiment, the amount mount 130 is a receiver hitch of a vehicle. The first tube section has a longitudinal axis 124 extending along the first tube section 104 from the first end 120 to the second end 122. In one embodiment, the first tube section 104 is formed from square metal tubing and has a hitch pin hole 126 adjacent the second end 122 of the first tube section 104. The hinge pin hole 126 is operable to receive a hitch pin when mounting the carrier 100 to a mount 130 (e.g., receiver hitch).

The second tube section 106 is affixed (e.g., welded) to the first tube section 104. The first tube section 104 is substantially centered with respect to the second tube section 106, and the second tube section 106 has a first end 132 and a second end 134 opposite the first end 132. The second tube section 106 is substantially horizontal when the carrier 100 is in an upright position (e.g., mounted in a vehicle's receiver hitch). The first cradle 108 is affixed to the second tube section 106 at the first end 132 of the second tube section 1064 106 or at a point adjacent to the first end 132 of the second tube section 106. The second cradle 110 is affixed to the second tube section 106 at the second end 134 of the second tube section 106 or at a point adjacent to the second end 134 of the second tube section 106. The second cradle 110 is operable to support the rollator for transportation on the carrier 100 in cooperation with the first cradle 108. In one embodiment, the first cradle 108 and the second cradle 110 each comprise a pair of protrusions extending generally upwardly from the second tube section 106 when the second tube section 106 is in an upright position for receiving the rollator 102. In one embodiment, the second tube section 106 is split into two portions. A first portion is welded to the first tube section 104 on a first lateral side of the first tube section 104, and a second portion of the second tube section 106 is welded to a second lateral side of the first tube section 104 opposite the first lateral side of the first tube section 104.

The third tube section 112 is operable to engage the secondfirst end 120 of the first tube section 104. The third tube section 112 is operable to rotate about the longitudinal axis 124 of the first tube section 104. In one embodiment, the third tube section 112 is rounded adjacent a second end 142 of the third tube section 112 opposite the first end 138 of the third tube section 112. The third tube section 112 is operable to fit within or over a portion of the first tube section 104 adjacent the first end 120 of the first tube section 104 such that the longitudinal axis 136 of the third tube section 112 substantially co-linear with the longitudinal axis 124 of the first tube section 104.

In one embodiment, the first tube section 104 has an alignment hole 150 adjacent the first end 120 of the first tube section 104. The third tube section 112 has a first hole 154 operable to align with the alignment hole 150 in the first tube section 104 when the fourth tube section 114 is substantially parallel to the second tube section 106. An alignment penpin 156 is operable to engage the alignment hole 150 and the first hole 154 of the third tube section 112 to maintain the fourth tube section 114 andin a position substantially parallel to the second tube section 106. The third tube section 112 also has a second hole 152 operable to align with the alignment hole 150 in the first tube section 104 when the fourth tube section 114 is substantially vertical and the carrier 100 is in a substantially upright position (e.g. managed mounted to a vehicle's receiver hitch). The alignment penpin 156 is further operable to engage the alignment hole 150 and the second hole 152 of the third tube section 112 to hold or maintain the fourth tube section 114 in the substantially vertical position. In one embodiment, the alignment hole 150 is in a top surface of the first tube section 104, and the alignment penpin 156 is tethered to the carrier 100 at, for example, the fourth tubing section 114. In another embodiment, the alignment penpin 156 is a spring-loaded pin affixed to a lateral side of the first tube section 104, and the alignment hole 150 is on a lateral surface of the first tube section 104. In such an embodiment, the alignment pin 156 is operable to engage the alignment hole 150 and the first hole 154 of the third tube section 112 to maintain the fourth tube section 114 in the substantially upright position and to engage the alignment hole and the second hold 152 of the third tube section to maintain the fourth tube section in a position substantially parallel to the second tube section 106. The lateral surface (or lateral side) of the first tube section 104 is a vertical portion of the first tube section 104 when the carrier 100 is in an upright position.

The fourth tube section 114 is affixed to the third tube section 112 (e.g., welded) and extends substantially perpendicularly from the third tube section 112. The fourth tube section 114 is affixed to the third tube section 112 at a first end 138 of the third tube section 112 or at a point adjacent to the first end 138 of the third tube section 112 at or and at a point adjacent to a first end 140 of the fourth tube section 114.

The clamp 116 extends from the fourth tube section 114. The clamp 116 is operable to secure the rollator 102 to the carrier 100 by engaging the rollator 102 and preventing the rollator 102 from bouncing out of the first cradle 108 and the second cradle 110 while the rollator 102 is being transported on the carrier 100. In one embodiment, the clamp 116 extends from a second end 160 of the fourth tube section 114 opposite the first end 140 of the fourth tube section 114. The clamp 116 includes a spring 162, a hook 164, and a handle 166. The spring 162 is connected to the clamp 116 and anchored to the fourth tube section 114 to bias the clamp 116 into the second end 160 of the fourth tube section 114. The hook 164 has a first portion 170 extending generally perpendicularly from the fourth tube section 114 and a second portion 172 extending generally parallel to the fourth tube section 114 toward the first end 140 of the fourth tube section 114. A handle 166 extends generally perpendicularly from the fourth tube section 114 in a direction generally opposite the first portion 170 of the hook 164.

Referring to FIG. 2, the carrier 100 is shown mounted in a receiver hitch of a vehicle. Referring to FIG. 3, the carrier is shown with an arm of the carrier (i.e., the fourth tubingtube section 114 and parts attached thereto) in a down or horizontal position. The rollator 102 can then be placed in the first carrier 108 and second carrier 110 to support the rollator 102 on the carrier 100. The arm is rotated into a vertical position and secured via the alignment hole 150 as described above. The handle 166 is then used to pull the clamp 116 out of the second end 160 of the fourth tubing section 114 and secure the hook 164 of the clamp 116 on to the rollator 102 holding the rollator 102 into the first cradle 108 and second cradle 110 for transportation as shown in FIG. 4. Alternatively, the hook 164 of the clamp 116 may extend away from the second end 122 of the first tubingtube section 104. In this embodiment, the user would position the rollator 102 in the first cradle 108 and second cradle 110, push the rollator against the fourth tubingtube section 114 and hook 164, and then use the handle 166 of the clamp 116 to secure the hook 164 onto the rollator 102.
